All kinds of vehicle manufacturers will have to mandatorily provide detailed declaration about the emission levels of each vehicle they manufacture from April next year.

In an official statement issued on Tuesday, the road transport ministry said Form 22 under the Central Motor Vehicles Act, 1989, has been amended. Through the revised Form 22, manufacturers would have to provide initial certificate of compliance with pollution standards, safety standards of components quality and road–worthiness certificate for all vehicles.

“Earlier, Form 22 only certified that the vehicle in question complied with the provisions of the Motor Vehicles Act and rules there under, including the relevant emission norms — Bharat Stage I/II/III etc,” it said.

The revised form would include the brand, chassis number, engine number and emission norms etc of the vehicle and specify the levels of each pollutant like carbon monoxide for petrol and diesel vehicles, and also sound level for horn and pass by noise values.

“The amended rules will apply to all vehicles run on petrol, CNG, LPG, electric, diesel and hybrid, including agricultural and construction vehicles, as well as e-rickshaws and e-carts,” the statement said.

Form 22 would be issued with the signature of the manufacturer. In the case of e-rickshaws and e-carts, this form would be issued with the signature of an authorised signatory of registered e-rickshaw or e-cart association.
